Transition metal nanostructures coated with a contiguous, conformal submonolayer-to-multilayer noble metal film and their method of manufacture are described. The manufacturing process involves the initial formation of suitably sized transition metal or alloy nanostructures which may be nanorods, nanobars, or nanowires. A monolayer of a non-noble metal is deposited onto the surface of the nanostructures by underpotential deposition. This is followed by the galvanic displacement of the non-noble metal by a second metal to yield a conformal coating of a monolayer of the second metal on the surface of the nanostructures. The replacement of atoms of the first metal by atoms of the second metal is an irreversible and spontaneous redox reaction which involves the replacement of a non noble metal by a more noble metal. The process can be controlled and repeated to obtain the desired film coverage. The resulting coated nanostructures provide heightened catalytic activity and can be used as high-performance electrodes in fuel cells.

High voltage semiconductor devices with high-voltage termination structures are constructed on lightly doped substrates. Lightly doped p-type substrates are particularly prone to depletion and inversion from positive charges, degrading the ability of associated termination structures to block high voltages. To improve the efficiency and stability of termination structures, second termination regions of the same dopant type as the substrate, more heavily doped than the substrate but more lightly doped than first termination regions, are positioned adjoining the first termination regions. The second termination regions raise the field threshold voltage where the surface is vulnerable and render the termination structure substantially insensitive to positive charges at the surface. The use of higher dopant concentration in the gap region without causing premature avalanche is facilitated by only creating second termination regions for regions lacking field plate protection.
